Description

The Model 091-150-115 A.C. Auto Pump Timer is designed expressly for the Models 091-9B-1-AD, 091-9HP, and 091-9HP-AD Auto Pumps. The timer reduces pump wear and extends pump life by limiting the duty cycle to one hour running followed by a one hour "OFF" time. When an AC Auto Pump is installed in a vehicle that experiences high air leakage, the pump continuously runs. This continual running creates higher temperatures and high wear rates reducing the pumps efficiency and life. Easily installed, the timer has no effect on normal pump operation, and assures long AC Auto Pump life.
